因此，我正在使用Jetbrans Rider上的mono在ubunto上开发一个asp.net mvc应用程序。 我尝试通过使用linq to sql进行分组时遇到此错误：
`var query = from product in context.ProductBasket
where product.NoSeller == NoSeller
orderby product.DateCreation ascending
group product by product.NoClient into g
select g;`
System.Data.SqlClient.SqlException

我打开了Windows和Visual Studio，但并没有遇到这个问题，一切都很好...
有人知道为什么吗？
